Adjust the fade, contrast, and monochrome settings of a PDF underlay.
If you select a single PDF underlay, the default values for Fade, Contrast, and Monochrome are the current property settings of the selected underlay. If you select multiple underlays, the default values for Fade, Contrast, and Monochrome remain as they were set the last time the command was used.
You can adjust the colors for the background of the PDF with the Properties Palette.
The following prompts are displayed.
Controls the fade effect of the underlay. Values range from 0 through 100. The greater the value, the lighter the linework in the underlay appears. Works indirectly with the contrast effect; a higher contrast value blends the underlay in the background when fade is set to a higher value.
Controls the contrast, and indirectly the fading effect, of the underlay. Values range from 0 through 100. The greater the value, the more each pixel is forced to its primary or secondary color. Default=75.
Controls the color saturation of all linework while maintaining the luminance. When turned on, the linework appears in varying shades of gray starting at black if the background color luminance is 50 percent or more. If the background color luminance is less than 50 percent, then the colors are inverted, with the darkest linework displaying in white, and the lightest linework displaying in black.
